Comparisons and Research on the Comprehensive Performance of Stainless Steel Clad Steel Bars
By comprehensively comparing the corrosion resistance,tensile and bending mechanical properties before and after corrosion of ordinary carbon steel,epoxy coated steel bars,stainless steel coated steel bars,and stainless steel bars,the application of stainless steel coated steel bars in bridge engineering is explored and promoted.The results of salt spray corrosion tests have verified that stainless steel coated steel bars have excellent durability performance,just like epoxy coated and stainless steel bars;the research results of tensile and bending mechanical properties before and after corrosion have verified that the ultimate strength,yield strength,elongation after fracture,and bending performance of stainless steel clad steel bars before and after corrosion can meet the requirements of the specifications,and their performance is better than that of ordinary steel bars;the comparative experimental study on the performance of epoxy coated steel bars and coated steel bars has verified that the damage resistance and anchoring performance of stainless steel coated steel bars are superior to those of epoxy coated steel bars.Research has shown that considering various factors such as mechanical properties,corrosion resistance,and engineering cost,the comprehensive performance of stainless steel coated reinforced concrete structures is superior to ordinary carbon steel concrete structures,epoxy coated reinforced concrete structures,and stainless steel reinforced concrete structures,which has high feasibility in the construction of marine environment bridge engineering.
